CPT® Code 85027 is used to report a complete blood count (CBC) performed using automated methods, without a differential white blood cell count. This test evaluates key components of blood, including red blood cells, white blood cells, hemoglobin, hematocrit, and platelets, providing essential information for a wide range of clinical conditions.
This code represents the automated CBC only, and does not include a differential (which would be reported with CPT 85025).
